Monsanto Co.’s best-selling weedkiller Roundup probably causes cancer, the World Health Organization said in a report that’s at odds with prior findings.

Roundup is the market name for the chemical glyphosate. A report published by the WHO in the journal Lancet Oncology said Friday there is “limited evidence” that the weedkiller can cause non-Hodgkin’s lymphoma and lung cancer and “convincing evidence” it can cause cancer in lab animals. The report was posted on the website of the International Agency for Research on Cancer, or IARC, the Lyon, France-based arm of the WHO.
